AUTOMATIC STORE-STOOL.

SPECIFICATION forming part of Letters Patent No. 791,268, dated May 30,1905.

Application filed February 25, 1905. Serial N0. 247,233.

T0 (LN 11111/0111/ i/ mfflfl/ cm1/cern:

Be it known that I, JosEPH JAMEsoN, a citi- Zen of the United States,residing at Toledo, in the county of Lucas and State of Ohio,haveinvented certain new and useful Improvements in Automatic Store-Stools;and I do declare the following to be afull, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the iigures of reference marked thereon,which form a part of this specification.

My invention relates to that class of seats known as automaticcounter-stools, the one leg of the stool being pivotally supported uponthe floor and having a spring to hold the pivoted stool against or nearto the counter when unoccupied.

My invention is designed more particularly to provide means foradjusting the tension of the spring which controls the position of thestool-leg, to provide stops to limit the movement of the stool-leg,which stops shall be independent of the Hoor-plate upon which thestool-leg is pivoted and which stops may be adjusted independently ofthe floor-plate, to provide a construction in which the spring abovereferred to shall be entirely concealed and protected, and to providenovel and efiJ cient means for securing the spring against displacement.I attain these objects by means of the devices and arrangement of partshereinafter described and shown, and illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation of my stool, showing thecounter, Hoor-plate, and stopplate hereinafter referred to in sectionand showing the seat in dotted lines in position for use; Fig. 2, a topplan View of the stopplate hereinafter referred to detached; Fig. 3, atop plan view of the spring adjustingpiece hereinafter referred to; Fig.4, a central transverse section of the door-plate, and Fig. 5 a centrallongitudinal sectional elevation of the same.

Like numerals of reference indicate like parts throughout the drawings.

In the drawings, 1 is a stool-leg having secured to its top in anydesired manuel' and in operative relation a seat 2.

3 is a recessed floor-plate secured to the floor by screws and into thehollow of which projects the lower end of the leg 1. Through the sidesof the recess of the floor-plate and transversely through theleg nearits lower end are coincident holes 4, through which passes a pivot-pin5, upon which the lower end of the stool-leg is pivoted and swings. Inthe side of the floor-plate next to the counter is an opening oreilt-away portion 6, in which is a flat plate 7, which rests upon and issecured directly to the floor independently of the Hoor-plate by meansof screws 8.

Projecting downwardly from the lower end of the stool-leg is a lug 9,which when the stool is swung toward the counter engages shoulders 10upon the plate 7 and which when the stool-leg is swung into position foroccupancy, as indicated by the dotted lines in Fig. 1, engages shouldersor stops 10 on the plate 7. It will be seen that the shoulders 10 10aform stops which limit the throw of the stool-arm in both directions.

11 is a coiled spring, one end of which encircles and engages a spur 12,projecting from the side of the lug 9, the other end of the springengaging in the same manner a spur 13 on the end of a block 14, having afiat extension 15. In this extension is a slot 16, through which passesa set-screw 17 into a screw-hole 18 in plate 7. The block 14 rests uponthe top of the plate 7 and by means of the set-screw 17 in the slot 16is adjustable toward and away from the spring 11. It will be seen thatthe tension of the spring 11 may be regulated by moving the block 14into the desired position and then securing it by means of the setscrew17.

My stool is assembled by first fastening the plate 7 to the floor. Theplate 3, with the leg 1 and pivot 5 in place, is next moved to exactlythe position required to insure the cooperation of the shoulders 10 1()awith the lug 9 at the proper points, and the plate 3 is then secured tothe Hoor by screws or otherwise.

The spring 11 is now inserted through the opening 6, so that the innerend of the spring encircles the spur 12. The block 14 is next insertedinto the opening 6, with the spur 13 engaging the outer end of thespring 11. Block 14 is pushed inwardly far enough to give the springexactly the right tension and is then Secured in position by means ofthe set-screw 17. Now the stool will when unoccupied be forced by thespring to the position shown by the solid lines in Fig. 1, and when thestool is occupied it is moved with the hand or foot into positionindicated by the dotted lines in Fig. 1. When the sitter arises, thestool is automatically moved by the spring out of the way. Should thespring become weakened, its tension may be quickly adjusted, and it' itis broken it can be readily replaced by merely removing the block 14 andwithout disturbing any other part of the device. 1f the stool is to beused as a stationary stool, the block 14 may be moved into such positionthat the spring becomes inoperative.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

A stool comprising a recessed Hoor-plate, a stool-leg pivoted at itslower end upon said floor-plate and having at its upper end a seat, anextension upon the lower end of the leg, a plate having shoulders whichform stops for said extension, an adjustable member, means for securingsaid member in adjusted position, and a spring in the recess of theoorplate engaged with said leg extension and with said adjustablemember.

1n testimony whereof l aiiix my signature in presence of two witnesses.

JOSEPH JAMESON.
